Bush's speech and aerial attacks on the country, all convoys were staged to push to Baghdad. Weeks later, Bravo Company (-) reservists were the first of the battalion to set foot in Baghdad. Although destroyed bridges were an obstacle to many units, the AAV's ability to cross the major rivers was an integral part of the overall mission.
4th AABn has deployed company sized elements in support of Joint Task Force-Horn of Africa.
In the wake of Hurricane Katrina, Alpha Company 3rd Platoon Marines stationed at Naval Construction Battalion Center Gulfport, MS deployed when the backside of Hurricane Katrina was still pounding south Mississippi. The Marines ventured out into 70 plus mile per hour winds and navigated through a wall of water that Katrina dumped on Gulfport and Biloxi. At one point during the storm, the Marines picked up some Biloxi police and firefighters and together, they looked past the flooded roads and the storm soaked yards for anyone who appeared to be trapped.
Bravo Company (-) reservists from Jacksonville, Florida deployed to the New Orleans in support of rescue and recovery operations. The unit was active for an estimated three weeks until active duty units could arrive and take over operations. While in the Area of Operations (AO), B(-) ran rescue operation on a daily basis, even while Marines were injured due to the conditions after the destruction of the storm. B(-) made it to the AO within 96 hours of the storms passing, commanding the AAV-7A1 down the I-10 corridor. Upon arrival to New Orleans, in 10 AAV units, the Marines began to commence search and rescue operations before arriving at their base of operation at Michoud Assembly Facility in New Orleans.
